Eric Hautala -- the cog in the Microsoft machine responsible for Windows Phone 7's update mechanism -- has taken to the company's official Windows Phone blog today to deep-dive on some of the concerns, problems, and delays that have dogged the platform's updates so far. In brief, Hautala says that the glitches that hosed the small February update for a few customers has brought the company to pause and take the time to make sure everything's rock solid before proceeding with the so-called NoDo update -- which includes copy and paste, performance improvements, and CDMA support -- and had originally been scheduled for the early part of March. Now, they're looking at "the latter half of March," which lines up with what Microsoft France had reported yesterday. He goes on to say that the problems have zero effect on the timeline for awesome new features previewed at MWC last month, which would seem to allay fears that the Mango update had been pushed to 2012. Needless to say, Windows Phone's still got some catching up to do -- so that's good news.
